Magic. That's what these warm white LED microlights on delicate strands of silver wire create as they twinkle in the darkness. Wrap or drape lengths around your garden structures and you'll swear you have a charm of fairies out there — dancing to delight and enthrall you. A waterproof battery pack with programmable timer lets you set your own spellbound sessions. Guaranteed to last at least 50,000 hours: if you kept the magic going 7 days a week, for 6 hours out of every 24, that equals just about 23 years!
